  Donations

  Museum 
  : 
  Specimen 
  of 
  Durangite, 
  from 
  Du- 
  

   rango, 
  Mexico, 
  by 
  Henry 
  G. 
  Hanks. 
  

  

  Mr. 
  Hanks, 
  in 
  presenting 
  the 
  above 
  mineral, 
  remarked 
  that 
  it 
  

   was 
  supposed 
  to 
  exist 
  in 
  considerable 
  quantity 
  in 
  Durango 
  ; 
  that 
  

   heretofore 
  it 
  had 
  been 
  quite 
  rare 
  ; 
  it 
  had 
  no 
  special 
  value, 
  and 
  is 
  

   prized 
  only 
  as 
  a 
  curious 
  formation. 
  

  

  Dr. 
  Gibbons 
  exhibited 
  specimens 
  of 
  tape-worms 
  engendered 
  in 
  

   the 
  system 
  of 
  a 
  child. 
  These 
  worms 
  were 
  of 
  a 
  peculiar 
  form, 
  and 
  

   Dr. 
  Gibbons 
  supposed 
  they 
  were 
  caused 
  from 
  raw 
  meat 
  having 
  

   been 
  fed 
  to 
  the 
  child 
  for 
  some 
  disease 
  of 
  the 
  bowels. 
  They 
  were 
  

   beef 
  tape- 
  worms 
  ( 
  Tcenia 
  mediooanellata) 
  ; 
  the 
  child 
  recently 
  began 
  

   to 
  discharge 
  isolated 
  worms 
  presenting 
  a 
  notched 
  joint 
  at 
  one 
  end, 
  

   and 
  the 
  other 
  end 
  rounded 
  more 
  like 
  a 
  head. 
  On 
  further 
  exami- 
  

   nation 
  under 
  the 
  microscope, 
  the 
  head 
  in 
  one 
  specimen 
  was 
  found 
  

   to 
  protrude 
  half 
  an 
  inch. 
  No 
  description 
  of 
  the 
  isolated 
  creature 
  

   was 
  found 
  in 
  the 
  books 
  by 
  Dr. 
  Gibbons. 
  It 
  differs 
  from 
  the 
  ordi- 
  

   nary 
  detached 
  segments 
  of 
  tape-worm 
  in 
  the 
  apparent 
  possession 
  of 
  

   a 
  head 
  at 
  the 
  rounded 
  extremity, 
  approaching 
  in 
  this 
  respect 
  the
